Impact of right ventricular dysfunction on outcomes in patients requiring intra-aortic balloon pump placement: A retrospective nationwide analysis (2016-2020).

Right ventricular dysfunction (RVD) continues to be a significant contributor to both mortality and morbidity, posing a significant challenge in the management of patients undergoing evaluation for mechanical circulatory support (MCS). Currently, there is a paucity of data regarding outcomes in this subset of patients. We analyzed the National Inpatient Sample database (NIS) to identify adult hospitalizations who underwent intra-aortic balloon pump (IABP) placement with or without co-existence of RVD. Multivariate logistic regression, and linear regression analyses were used to compare outcomes, and adjust for possible confounders. Out of 126,985 hospitalizations who underwent IABP placement, 1,475 (1.2%) had RVD. Patients with RVD who received an IABP had higher adjusted odds of inpatient mortality (Adjusted odds ratio [aOR]: 2.33, 95% confidence interval [CI]: 1.7-3.2, p<0.001) than those without co-existing RVD. Hospitalized patients who underwent IABP placement with RVD had higher adjusted odds of worse hospitalization outcomes in general. Conducting additional prospective studies and clinical trials with an emphasis on further subcategorization of patients with RVD is crucial for determining optimal management strategies for these patients.

Impact of Co-existing Paroxysmal Atrial Fibrillation on Different Outcomes of Hospitalized COVID-19 Patients: Nationwide Inpatient Sample Analysis (2020) With Propensity Score Matching.

Various studies in the medical literature reported significant cardiovascular involvement in patients with coronavirus disease 2019 (COVID-19) pneumonia. Atrial fibrillation (AF) was identified as the most commonly observed arrhythmia complicating COVID-19 infection with an increased risk of short-term mortality. We used the National Inpatient Sample Database (NIS) of 2020 to conduct this retrospective cohort study. Our study's population consisted of adult patients hospitalized for COVID-19 Pneumonia with or without the presence of paroxysmal atrial fibrillation (PAF). Encounters with COVID-19 and co-existing PAF had higher adjusted odds of inpatient mortality (Adjusted odds ratio [aOR]: 1.19, 95% CI: 1.11-1.28, P < 0.001), longer mean length of hospital stay (LOS) of 1.17 days (95% confidence interval [CI]: 1.03-1.38, P < 0.001), and higher odds of different in-hospital complications. Based on these results, conducting more prospective/retrospective cohort studies with an emphasis on long-term follow-up on patients who develop PAF following COVID-19 infection is warranted.

Clinical Characteristics of Sarcoidosis Patients with Self-Reported Lymphoma: A US Nationwide Registry Study.

PURPOSE: Little is known about the association between sarcoidosis and lymphoma. We aim to determine the prevalence of lymphoma in US sarcoidosis patients and compare the clinical characteristics of patients with and without lymphoma. METHODS: Using a national registry-based study investigating 3560 respondents to the Foundation for Sarcoidosis Research Sarcoidosis Advanced Registry for Cures Questionnaire (FSR-SARC) completed between June 2014 and August 2019, we identified patients who reported the diagnosis of lymphoma following sarcoidosis and randomly selected a computer-generated control sample of sarcoidosis patients with no reported lymphoma with a 2:1 ratio. RESULTS: Among 3560 patients with sarcoidosis, 43 (1.2%) reported developing lymphoma following their sarcoidosis diagnosis. Patients with lymphoma were more likely to be diagnosed with sarcoidosis at a younger age (median, IQR) 40 (27-50) vs 45 (34.8-56, p = 0.017) years, were more likely to be African-Americans OR 95% CI 3.9 (1.6-9.6, p = 0.002), and have low annual income (OR 2.7, 1.1-6.4 p = 0.026). The sarcoidosis-lymphoma group were more likely to have salivary gland (16% vs 5%, p = 0.026) (OR 4; 1.1-14.5) and cutaneous (46% vs 23%, p = 0.023) (OR 2.9; 1.1-7.3) sarcoidosis. They also reported more chronic fatigue (42% vs 23%, p = 0.029), chronic pain (37% vs 13%, p = 0.001), and depression (42% vs 22%, p = 0.019). CONCLUSION: The prevalence of lymphoma reported in sarcoidosis patients is higher than the general population which further supports the possible increased risk of lymphoma in sarcoidosis. Diagnosis of sarcoidosis at a younger age, African-American race, cutaneous, and salivary glands sarcoidosis were associated with lymphoma. Sarcoidosis patients who developed lymphoma reported higher disease burden and more non-organ-specific manifestations.
